malloc_stats(3)         Library Functions Manual         malloc_stats(3)

NAME

       malloc_stats - print memory allocation statistics

LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #include <malloc.h>

       void malloc_stats(void);

DESCRIPTION

       The malloc_stats() function prints (on standard error) statistics
       about memory allocated by malloc(3) and related functions.  For
       each arena (allocation area), this function prints the total
       amount of memory allocated and the total number of bytes consumed
       by in-use allocations.  (These two values correspond to the arena
       and uordblks fields retrieved by mallinfo(3).)  In addition, the
       function prints the sum of these two statistics for all arenas,
       and the maximum number of blocks and bytes that were ever
       simultaneously allocated using mmap(2).
